Find X if f(x)=18x+26 and f(x) = 2x+10

x = -1

Step-by-step explanation:

Start out by making the equations equal to each other since we are trying to find x (if x is the same for both equations, which it is for this problem due to the equations shown above).

18x + 26 = 2x + 10

Now that the equation is set up to find x, we need to get x by itself. Now subtract 2x on all sides to get all the x variables on the same side. Apply the same logic for the normal numbers by subtracting 26 on all sides to get the normal numbers on one side. You should end up with the numbers shown below for this step:

18x + 26 = 2x + 10

-2x   -26   -2x  -26

16x = -16

For the final step, remember that we want x by itself, so we have to divide both sides by 16 to get x by itself. After dividing both sides, you should end up with x = -1.

16x = -16

16      16

x = -1
